Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To make diagnosable accurately the deteriorated state of an insulator regardless of the influence of temperature or humidity at the time of diagnosis.

Title: Wire bonding method
Inventor: ABE MAKOTO
IPC: H01L21/60
Filed: 1985-07-31
Abstract: PURPOSE:To prevent the irregularity of a wire bonding by freely altering the magnitude of a colliding load. CONSTITUTION:When a capillary is abruptly dropped from a position 1, it is controlled from a position 2 several hundreds microns above a position to be predicted for collision to a die surface at an equal speed. The slope of a line to a horizontal plane indicates the speed of a capillary 23 to indicate that, the more sharp the slope is, the higher the speed is. When the capillary collides with the die surface, i.e., when the capillary is moved to a position 3, the equal speed control is altered. Thus, the collision to the die surface is detected from the variation of the speed, and a load P necessary to form eutectic crystal in a sphere of gold wire on the die surface is applied. Then, the capillary is fed through positions 4, 5 to a position 6, and leads 22 are controlled at the speed and pressurized. Thus, when the equal speed control is achieved between the positions 2 and 3 and a mechanical contact is detected at the position 3, a CPU immediately produces a signal for applying a load to mechanically pressurize the load.

Abstract: PROBLEM TO BE SOLVED: To facilitate execution work, attain weight reduction and cost reduction, and also prevent infiltration of rainwater by integrally forming a rafter clearance part having a rafter clearance closing member and a ridge tile receiving stand extending from its upper end, in a rear part of a pantile. SOLUTION: A rafter clearance part 3 having a rafter clearance closing member 8 and a ridge tile receiving stand 9 extending in the operation length direction from its upper end, is integrally formed in an operation length directional rear part of a pantile part 2. When a pantile 1 having this rafter clearance closing member is executed on the ridge or the like of a roof tile laying roof, since there is no clearance in a boundary between the rafter clearance closing member 8 and a pantile part 2, rainwater does not infiltrate. Even if rainwater infiltrate into a part on the ridge tile receiving stand 9, it does not infiltrate up to the inmost part coupled with an inclination of the ridge tile receiving stand 9.  Since execution work can be performed without practically using laying earth, weight reduction can be attained, and cost reduction can be expected, and a change with the lapse of time is reduced, and durability of a ridge part can be improved.

IPC: H03L7/00
Filed: 1994-07-21
Abstract: PURPOSE:To attain stable clock recovery independently of a reception state or a content of received data by replacing a clock signal extracted from a burst signal with a reference clock signal. CONSTITUTION:A clock extract circuit 52 extracts a clock signal and the signal is outputted as a clock output 5 via a time limiter circuit 53 and a 2:1 selection circuit 4 and given to a timing generating circuit 6. A reference clock signal outputted from a 1/N frequency divider circuit 2 and the clock output 5 are synchronized based on a load pulse generated by the circuit 6. Thus, after the phases of the two clock signals are matched with each other, an external selection signal 3 is given to the circuit 4 to allow the circuit 4 to replace the clock signal extracted from the burst signal with the reference clock signal outputted from the circuit 2 as the clock output 5. Thus, stable clock recovery is executed at all times.

Abstract: PURPOSE:To enable a user to obtain a proper menu display without paying any attention to the kind of data by discriminating a menu corresponding to data which is inputted from outside and displaying a menu picture corresponding to the discriminated menu. CONSTITUTION:A CPU 5 inputs the data for menu discrimination from an external storage device 11, stores the data in an area 7-1 for the data for menu discrimination.

IPC: B23D55/08
Filed: 1989-07-03
Abstract: PURPOSE:To prevent the tipping and wear from occurrence without bringing the tip of a saw blade into contact with the end surface of a work by a method wherein when a saw blade is returned from a cutting completion position to a start position, the end surface of the work is separated away from a cutting surface. CONSTITUTION:When a cutting work is effected, after a band saw blade 29 is temporarily stopped in a cutting completion position located below a work, it is returned to its original start position. In this case, pressure oil is fed to a port A, and when pressure oil is bled through a port B, the whole of a saw blade housing 5 is moved in the direction of an arrow mark C. The saw blade housing 5 is raised in a state that it is separated away from the cut surface of a work, and the band saw blade 29 is returned to a start position. Since, when the band saw blade 29 is returned from the cutting completion position to the start position, it is located in a position it does not make contact with the cut surface of the work and is separated away therefrom, the tip of the band saw blade 29 is prevented from the occurrence of tipping and wear, and a band saw blade 29 life can be increased.
